Description

Vereinigtes Anlaß- und Sicherheitsventil für Verbrennungskraftmaschinen. Das Anlaßventil von, Verbrennungskraftmaschinen derart auszubilden, daß es auch als Sicherheitsventil _ gegen übermäßige Drucksteigerung im Zylinderinnern wirkt, ist bekannt. Bei Einrichtungen dieser Art .hat man das Ventil derart auf seinem Sitz angeordnet, daß es sowohl beim Eintritt von Anlaßluft als auch beim Auftreten unzulässig hoher Drücke nach außen sich öffnet. Hierbei müssen besondere Organe, wie Schieber o. dgl, im Innern des Ventilgehäuses vorgesehen sein, um zu verhindern, daß die aus dem Zylinderraum ausströmenden Gase in die Anlaßleitung gelangen. Ferner ergibt sich bei nach außen öffnenden Ventilen eine größere Drosselung der Anlaßluft oder ein größerer Ventilhub.United starting and safety valve for internal combustion engines. The starter valve of internal combustion engines to train in such a way that it also acts as a safety valve _ against excessive pressure increase inside the cylinder, is known. With devices of this type .has the valve on his Seat arranged that there is both the entry of starting air and the occurrence Inadmissibly high pressures open to the outside. Special organs must be like slider o. the like, be provided in the interior of the valve housing, to prevent the gases flowing out of the cylinder chamber from entering the starting pipe reach. Furthermore, there is a greater throttling in the case of outward opening valves the starting air or a larger valve lift.

Die Einrichtung gemäß vorliegender Erfindung kennzeichnet sich dadurch, daß das Sicherheitsventil vom Gehäuse des Anlaßventils gebildet wird. Hierbei ist es möglich, das Anlaßv entil in üblicher Weise sich nach innen öffnen zu lassen, ferner sind die Wege der Anlaßluft und der dem Zylinder entströmenden Gase von vornherein getrennt, so daß ein Vermischen unmöglich und besondere Vorkehrungen dagegen entbehrlich sind. Das neue Ventil ist einfach und übersichtlich und daher auch billig herzustellen.The device according to the present invention is characterized by that the safety valve is formed by the housing of the starter valve. Here is it is possible to let the starter valve open inwards in the usual way, furthermore, the paths of the starting air and the gases flowing out of the cylinder are a priori separated so that mixing is impossible and special precautions are not necessary are. The new valve is simple and clear and therefore cheap to manufacture.

Die Zeichnung veranschaulicht den Er= findungsgegenstand an einem Ausführungsbeispiel.The drawing illustrates the subject of the invention on one Embodiment.

Das Anlaßv entil d kann in beliebiger Weise, beispielsweise durch die Anlaßluft selbst oder, wie gezeichnet, mittels Schwinghebel und Nocken gesteuert werden. Das Gehäuse b, c des Ventils ist zweiteilig ausgebildet, von denen der obere, c, fest im Zylinderdeckel d, der andere, b, verschiebbar gelagert ist. Eine starke, dem zulässigen Höchstdruck im Zylinderraum angepaßte Feder e drückt den verschiebbaren Gehäuseteil b auf seinen Sitz f im Zylinderdeckel. Eine weitere Feder g hält in bekannter Weise das Ventil a in Schlußlage. Der Einlaßstutzen für die Anlaßluft ist mit la bezeichnet. Am unteren Ende des Gehäuseteils b wird von diesem und dem Zylinderdeckel d der Ringraum i gebildet, welcher beim Anheben des Teils b mit dem Innern des Zylinders verbunden wird, so daß die ausströmenden Gase durch die Bohrung k im Zylinderdeckel d ins Freie entweichen können. Die Wirkungsweise ist ohne weiteres verständlich.The starting valve d can be controlled in any way, for example by the starting air itself or, as shown, by means of rocker arms and cams. The housing b, c of the valve is constructed in two parts, of which the upper one, c, is fixedly mounted in the cylinder cover d, the other, b, is slidably mounted. A strong spring e adapted to the maximum permissible pressure in the cylinder space presses the displaceable housing part b onto its seat f in the cylinder cover. Another spring g holds the valve a in the final position in a known manner. The inlet connection for the starting air is denoted by la. At the lower end of the housing part b, the annular space i is formed by this and the cylinder cover d, which is connected to the interior of the cylinder when the part b is lifted so that the gases flowing out can escape into the open through the bore k in the cylinder cover d. The way it works is easy to understand.
